LOCK.

Application filed April 22, 1925. Serial No. 25,084.

This invention relates to improvements in looks and more particularly to those of this: double-eXtension-bolt type, operable by a ey.

One object of the invention is to so construct the lock that a single tumbler con nected and movable with one of the bolts shall be operable to lock both bolts in either projected or retracted position.

With this and other ojects in view, the invention consists in certain novel features of construction and combination of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings;

Figure 1, is a plan view of a lock em bodying my invention;

Figure 2, is a similar view, with the cover plate removed and the bolts locked in retracted position;

Figure 3, is a view similar to figure 2, with the bolts locked in projected position;

Figure i, is a sectional view on the line H of Figure 2;

Figure 5, is a perspective view of the tumbler, and

Figure 6, is a view showing the bolts.

In the construction of my improved look, I employ a casing 1 having side and end walls 2, 3 and a cover plate 4:, the latter having depressed portions 5 to act as guides and retaining means for bolts 6, 6, which are mounted to slide on the bottom of the casing and guided by the side walls 2 of the latter,the outer ends of said bolts being adapted to project through suitable openings in the end walls 3 of the casing. The casing may also be provided with stops 8, 8 to limit the inward throw of the bolts and shoulders 9 on the bolts cooperate with end walls oi the casing to limit the outward movement of said bolts.

Each bolt is provided intermediate its ends with a key notch 10, and at respective the inner edge of each bolt is recessed as at 11 for the accommodation of a fiat key 12 which enters between the bolts. A revoluble key guide 13 is mounted in the cover plate 4 and the casing may be provided with a hole or socket for the accommodation of a projection 14 on the end of the key. Between the key notch 10 and the outer end portion 7 of each bolt 6, spaced notches 15, 16, (each of which may be made flaring) and between the key notch 10 and the inner end, each bolt is provided with a notch 17, which latter may also be made flaring.

A tumbler 18 is disposed over the bolts and provided at one end with a head 19 which may have a rounded edge 20 to ride against one of the side walls 2 of the casing. The headed end of the tumbler is provided with a lateral lug 21 which loosely enters the flaring notch 16 in one of the bolts. The other end of the tumbler is provided with a finger 22 which normally engages one of the side walls of the casing, and this same end of the tumbler is provided with a lateral lug 23 to enter a notch 17 in one bolt and a notch 15 or 16 in the other bolt, a spring 24 secured to the headed end of the tumbler and engaging a side wall 2 of the casing, serving to retain the tumbler in or returning it to position to lock both bolts.

From the construction and arrangements of parts above described, it will be seen that the tumbler 18 has pivotal connection with one of the bolts and that it is cooperable also with the other bolt in a manner to have interlocking relation with the bolts to lock them in either projected or retracted position.

When the key is inserted in the space (afforded by the recesses 11) between the bolts, and turned, its edge portions will engage in the key notches 1'0, and as the tumbler spans the key notch in one of the bolts, the key will engage said tumbler and swing the latter suiiioiently on its pivotal connection with one of the bolts to cause the lug 23 to move completely out of one of the notches (15 or 16) of the other bolt. Continued turning of the key will now cause the two bolts to slide respectively in opposite directions, the tumbler moving with the bolt with which it is pivotally connected. When the bolts are in retracted position, a notch 17 in one bolt will align with a notch 16 in the other bolt, so that the lug 23 on the tumbler will project "from the notch 17 in one bolt and enter the notch 16 in the other bolt, thus interlocking the two bolts as shown in Figure 2. When the bolts are in projected position, interlocking will be efiected by the tumbler lug 23 in cooperation with the notch 17 in one bolt and the notch 15 in the other bolt (said notches being then in alignment) as shown in Figure 3.
